As part of a multimedia project that had never before been attempted, visual artist Alan Warburton created a virtual animation that highlighted not only Bach’s genius but also Warburton’s own creativity. Read more >>

Thanks. The link in that discussion was good but fairly limited. I have done some searches but can't seem to find a level of difficulty rating for Chopin's pieces, specifically. I am open to any other suggestions.

There is a website called Graded Piano Repertoire that grades piano solos from level 1-12 and compares different grading systems. It is a piano repertoire guide that also provides a lot of other information on the pieces in the database:

Thanks, monkeydudexd, for showing where there is a listing. On the basis of it, I've just discovered that I've been doing a multititude of grade 8 or 8+ pieces, and it's getting me really angry with certain people in this forum who impugned my qualifications to comment on a lot of the issues here.

Pretty useless, as already been mentioned. Not enough grade nuances.Prokofievs 3de concert 8+ together with a whole lot other 8+s, come on.And afterwards, piano pieces cannot be graded. Remember what Shnabel said on Mozarts sonates:'Too easy for beginners.....' you know.
